The Lowdown
Alright, surfers, Rusty here. Let's talk about what's on the table for Jaconé over the next couple of weeks.
Alright, so we’ve got a solid run of surf coming up, but it’s not all smooth sailing. The water is sitting at 72°F, which is pretty much what you’d expect for this time of year – nothing weird going on there.
The real action starts kicking off on Wednesday the 26th. We’ve got a serious pulse of energy moving in, with a combined swell energy of 2115 – that’s some proper grunt. The morning sees a 7ft south swell, but the wind is a cross-on from the west, so it’s a bit messy. The afternoon, though, is a different story. The swell jumps to 8ft from the south, with a very long 15-second period, and the wind swings to a cross-off from the ESE, making it clean. This is big, powerful, groundswell, and it’s going to be heavy. At 8ft, this is for experienced surfers only. The best of the day is definitely the afternoon, but be ready for some serious water moving around.
Thursday the 27th is where the magic really happens. The morning has a 8ft south swell, still with that long period, but now we’re getting a clean offshore from the NE. The wind stays offshore all day, and the afternoon drops a touch to a still-chunky 7ft. This is premium, glassy, offshore surf. The energy is still massive (2167 in the morning, 1759 in the afternoon), and the conditions are just about perfect for the crew that can handle it. This is the standout window of the whole forecast.
Friday the 28th the swell drops back to 4ft in the morning, still with clean offshore NE wind. It’s much more manageable, but the energy is way down to 540. It’s still a fun morning, but the afternoon gets a bit dicey with a stronger cross-off wind.
Saturday the 29th offers a mixed bag. The morning has a 6ft swell from the ENE, but the period is a short 8 seconds, so it won’t have much push. The wind is a light offshore, though, so it’ll be clean. The afternoon is a write-off.
Sunday the 30th is another standout morning. The swell is back up to 7ft from the ENE, but the best part is the wind: glassy. Absolutely zero wind. The energy is solid at 752, and it’s going to be like a lake out there. Perfect lines. This is a serious session for the experienced surfers again.
Monday the 31st keeps the good times rolling with clean, glassy conditions in the afternoon and a fun 5ft ENE swell. A great day for a wider range of surfers.
Things get a bit average from Tuesday the 1st of September into Wednesday the 2nd, with some poor conditions and onshore winds. But then Wednesday afternoon the 2nd of September shows a glimmer of hope with a 5ft SSW swell and a clean, cross-off breeze. The energy is moderate at 520.
The second week starts to look a bit more unpredictable. We’ve got a few days of onshore winds and rain, but there’s a notable window on Saturday the 5th of September with a clean 5ft south swell in the morning, and then again on Sunday the 6th of September with an offshore wind and a 4ft south swell. Later in the week, Wednesday the 9th of September looks promising for the experienced crew again, with a 7ft ENE swell and a solid offshore wind, giving it a combined energy of 1112. That’s a long-range call, so keep an eye on it.
Overall, the absolute best bet is Thursday the 27th, with those consistent offshore winds and solid, long-period south swell. Sunday the 30th is a close second with that glassy morning. Don’t sleep on Wednesday afternoon the 26th either, if you’ve got the skill for the size.
Stay safe out there.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
